What is a common indicator of septic system failure?

Pooling water in the yard is a common indicator of septic system failure because it suggests that the system is not functioning properly. A well-maintained septic system is designed to treat wastewater and allow it to seep into the ground through drain fields. When the system fails, the wastewater cannot be adequately processed or absorbed by the soil, leading to surface water pooling, foul odors, or even sewage backing up into the home. This visible accumulation of water can not only indicate a malfunctioning system but also poses health risks due to potential contamination of the surrounding environment.

In contrast, clear water discharge typically indicates that the system is functioning well, as treated water is expected to be clear after the treatment processes. Low electricity use does not provide any significant information about the condition of the septic system, since a well-maintained system may show low electricity use while still being functional. Strong pressure in pipes might suggest a blockage or issue but does not directly indicate a full system failure like pooling water does. Therefore, the presence of pooling water is a clear and tangible sign of septic system problems that require immediate attention.
